SEPTEMBER 23, 2009: The Australian Outback visits Sydney – the nation’s largest city. It was Nature reminding Man that it cannot be taken for granted and will not be ignored.

Man often thinks he can do anything. Clearing jungles, re-routing rivers, building cities. But it’s nothing to crow about as we are cautioned that with just a shudder, Mother Earth is always in control.

Imagine the power. With merely a breath, the planet can pick up five million tonnes of dust and dirt whip it into a front 800 kilometres long and drive it more than 1,100 kilometres from Central Australia to the east coast and out to the Pacific Ocean – all in less than a day. Coating anything and everything in its way, the dust storm caused havoc, stopping industry and transport and costing millions in lost productivity.

This planetary nudge was a reminder that from Dust we came and to Dust we will return. Man’s miniscule reign is just an itch in Earth’s four-billion year grandeur. All we are is Dust in the Wind.

Today I “attended” an educational technologies conference. Well sort of. I wasn’t there, but then again, I was. IWBnet’s “Leading a Digital School” conference was on at the Gold Coast in sunny Queensland and while I was unable to be a delegate at the venue, I had the next best thing. Many of the delegates who were there, were happy to instantly share their experience with the rest of the world via Twitter.
